The tale of the Snyder Cut will undoubtedly go down as one of the most fascinating stories in modern film history. It is one of the rare times that movie fans were able to rally together and champion an issue so much so that it actually came to fruition.
Like millions around the world, I've been waiting four years for the renowned #SnyderCut. I'll never forget sitting in the theater on opening night, witnessing a CGI mouth on Henry Cavill's face about five seconds into Justice League. That's a thing of nightmares if I must say. Anyways, right then and there, I knew I desperately needed Zack Snyder's film.
